[PATCH net-next 0/7] tcp: second round for EDT conversion

[Eric Dumazet <edumazet@google.com>]

First round of EDT patches left TCP stack in a non optimal state.

- High speed flows suffered from loss of performance, addressed
  by the first patch of this series.

- Second patch brings pacing to the current state of networking,
  since we now reach ~100 Gbit on a single TCP flow.

- Third patch implements a mitigation for scheduling delays,
  like the one we did in sch_fq in the past.

- Fourth patch removes one special case in sch_fq for ACK packets.

- Fifth patch removes a serious perfomance cost for TCP internal
  pacing. We should setup the high resolution timer only if
  really needed.

- Sixth patch fixes a typo in BBR.

- Last patch is one minor change in cdg congestion control.

Neal Cardwell also has a patch series fixing BBR after
EDT adoption.

Eric Dumazet (6):
  tcp: do not change tcp_wstamp_ns in tcp_mstamp_refresh
  net: extend sk_pacing_rate to unsigned long
  tcp: mitigate scheduling jitter in EDT pacing model
  net_sched: sch_fq: no longer use skb_is_tcp_pure_ack()
  tcp: optimize tcp internal pacing
  tcp: cdg: use tcp high resolution clock cache

Neal Cardwell (1):
  tcp_bbr: fix typo in bbr_pacing_margin_percent
